Add minimal test for basic hackathon operations and enhance test utilities

- Introduced a new test module for hackathon-related functionality.
- Implemented a basic test for creating a hackathon using a mock repository.
- Enhanced the test utilities in `lib.rs` for better request handling and response extraction.
- Added a `ServiceClient` struct to facilitate HTTP requests in tests.
- Created a `RequestBuilder` to streamline building and sending requests with headers and JSON bodies.
